Ok.
1. In view of the fact that the printer gets recognised, it's probably unlikely to be the cable, but still worth a check if all else fails.
2. Will assume from your answer that the Printers and Faxes folder is indeed blank.
3. Despite this port working with other devices, I'll assume you've tried other ports, particularly one directly attached to the motherboard, rather than one on a flying lead to the front panel, etc.
4. Worth checking...
5. Ok.
6. Ok. So probably not a software/driver issue.
7. Any facility on this Samsung for scanning or photocoying from its front panel?
8. Whilst this is never guaranteed to give any sort of results, it might be worth trying. Look in XP's selection of Samsung printers and see if there might be one which is near enough to yours, and try installing it. Might be worth a shot...
9. Can you try installing this printer on another machine?
If you're still not getting anywhere, it's starting to look like this could be a faulty printer, unless you know for sure otherwise...
